Is a .bt name registered?

Looked up from your browser in the registry's RDAP service; if that does not answer, in DNS. Nothing is stored on dnssec.in.

What this means

The root zone holds a DS record for .bt, so the extension is signed and anchored. A domain under .bt can use DNSSEC with a full chain of trust: it needs to be signed at its DNS host and have its own DS at the registrar. .bt is the country code for Bhutan; its registry sets who can register.

Second-level suffixes under .bt (5)

You can register names directly under .bt or under these suffixes, for example example.com.bt. Some are restricted to certain users (government, education, banks). Source: the Public Suffix List.

  • .com.bt
  • .edu.bt
  • .gov.bt
  • .net.bt
  • .org.bt

IDN names under .bt

No IDN tables for .bt at IANA: names are usually ASCII only (a–z, 0–9 and hyphen).

Length

DNS limits are the same everywhere: each label is 1 to 63 characters, the whole name at most 253, letters, digits and hyphens, not starting or ending with a hyphen. IDN labels count their xn-- form, so fewer native characters fit. A registry can set a higher minimum (often 2 or 3 characters) or reserve short names: that is in its own policy.

WHOIS and RDAP

This extension is not in IANA's RDAP list. There is no classic WHOIS server (port 43): since January 2025 ICANN lets gTLD registries offer RDAP only.

Lifecycle and drop

Country code extensions set their own lifecycle: grace periods, redemption and release dates differ from country to country and are not covered by ICANN's gTLD policies. Read the registry's rules: http://www.nic.bt.
